Abstract

This invention relates to a train noise isolation device and a train noise isolation method, which are applicable to a train path having sound insulation walls arranged on both sides. The noise isolation device includes a spray component and a controller. The spray component includes a pressurization motor electrically connected to the controller, a pressure accumulation barrel connected to the pressurization motor, and a sprinkler head set arranged on the sound insulation wall and connected to the pressure accumulation barrel. When a train leaves the train path, a signal is transmitted to the controller to make the spray component stop spraying water mist. With the water mist so sprayed, a transmission path of a sound wave of noise is extended, and the energy of the sound wave is gradually dissipated to further reduce the impact of noise on the surrounding residents.

The train is one of the main public transportation means for people to move long distances in daily life. However, when the train travels on the track, the train passes through the seam between the tracks and during the process of turning, the wheel and the track The collision and friction between them will produce high decibel noise, which in turn causes residents living nearby to be deeply disturbed by it.

In order to reduce the impact of the joints between the trains passing through the track and the noise generated during the cornering on the surrounding residents, the current practice is to install them on the sides of the roads that are prone to noise or on the sections with track joints. A soundproof wall.
